Answer:
b) 1
Step-by-step explanation:
![\frac{9}{6} \times \frac{2}{3} = \frac{18}{18}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B6%7D%20%20%5Ctimes%20%20%5Cfrac%7B2%7D%7B3%7D%20%20%3D%20%20%5Cfrac%7B18%7D%7B18%7D%20)
![\frac{18}{18} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B18%7D%7B18%7D%20%20%3D%201)
![\frac{-18z^{7}y^{5}-9z^{9}y^4+18z^6y^8}{9zy^{2} }= -2z^6y^3-z^8y^2+2z^5y^6](https://tex.z-dn.net/?f=%5Cfrac%7B-18z%5E%7B7%7Dy%5E%7B5%7D-9z%5E%7B9%7Dy%5E4%2B18z%5E6y%5E8%7D%7B9zy%5E%7B2%7D%20%7D%3D%20-2z%5E6y%5E3-z%5E8y%5E2%2B2z%5E5y%5E6)
When variables with exponents are divided by each other, you subtract the exponents.
For example:
![\frac{x^2}{x^1} = x^{2-1} =x^1](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2%7D%7Bx%5E1%7D%20%3D%20x%5E%7B2-1%7D%20%3Dx%5E1)
![\frac{x^5}{x^3} =x^{5-3} = x^2](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E5%7D%7Bx%5E3%7D%20%3Dx%5E%7B5-3%7D%20%3D%20x%5E2)
